Like before, I present here my newest keyboard controller firmware K.C.4 ("Kacey").
It allows editing everything like key mappings, layers, sequences/macros in real time on its display.
Now it is for Teensy 4.0 with a 320x240, 2.8" LCD display using ILI9341.
Full description on my website. Shorter with sources here.

Pictures and screens in gallery here.
A quick video (more on my channel).

My previous one was for Teensy 3.2 and 160x128 1.8" display. A bit cheaper solution that already did it all.
The new one is nicer to look at and use. Full comparison between them on my website.

Of course like all my keyboards I use since 2005 it features the rubber dome reduction, topic here.
